Mystery suspect who killed 2 officers deported twice before

A man authorities are having trouble identifying, but have in custody, was one of two suspects arraigned Tuesday after a crime spree that left two Northern California sheriff’s deputies dead.

Thirty-four-year-old Marcelo Marquez — also known as Luis Enrique Monroy-Bracamonte, the name authorities say matches the suspect’s fingerprints — was arrested Friday, along with his wife, in connection with the killing of Sacramento County sheriff’s Deputy Danny Oliver.

Oliver, 47, was shot in the forehead while investigating a suspicious car parked at a local Motel 6.   

Marquez and his wife, Janelle Marquez Monroy, 38, allegedly shot and wounded a driver in the face before carjacking him and another driver later.

One of those victims, Jose Cruz, recounted losing his truck to the suspect in an interview with the Sacramento Bee.

He told the paper that a man in a white Ford Mustang pulled up and asked him for his car keys. At gun point he complied and even helped the suspect disconnect a trailer from his work truck before watching him drive away.

The suspect later firied on Two Placer County deputies — killing one — with an AR-15-style weapon before fleeing again, KCRA Sacramento reported.

Homicide Det. Michael David Davis, Jr., 42, succumbed to his gunshot wounds at a hospital after the incident.

The Sacramento County Sheriff’s Department told KCRA that Marquez has many aliases and that it has not been able to confirm information from U.S. Immigration and Customs Enforcement officials to verify Marquez’s try identity.

“People do this every day with false birth records, false identifications, scams with Social Security numbers. It could have been a number of any of these but I cannot confirm at this time; it is part of this case investigation,” Sgt. Lisa Bowman told KCRA.

Under an alias, Marquez has been living in the U.S. illegally, according to reports. He was deported twice to Mexico, the first time after being convicted of selling drugs in Arizona in 1997, KCRA Sacramento reported.  He was deported again in 2001 and in 2003 received a year of probation and a $500 fine after a hit-and-run arrest in Utah.
